Since Podman 2.0.5, containers that were created with
'podman create --userns=keep-id ...' automatically get the user added
to /etc/passwd [1]. However, this user isn't as fully configured as it
needs to be. The home directory is specified as '/' and the shell is
/bin/sh.
Note that Podman doesn't add the user's login group to /etc/group [2].
This leads to the following error message when entering the container:
/usr/bin/id: cannot find name for group ID 1000
It's expected that this will be fixed in Podman itself.
Therefore, the entry point needs to call usermod(8) to update the user,
instead of using useradd(8) to create it.
